package/gettext-tiny: fix install failure if path contains "m4/" string

When building with path containing "m4/" occurence(i.e. make
O=output-m4) gettext-tiny install recipe copies files to wrong place and
later some package using autotools fail to autoreconf(i.e. minicom).
This is due to buggy gettext-tiny Makefile install recipe where they
substitute every "m4/" in INSTALL destination path, including the "m4/"
part of our build folder. Add patch to fix this by using $(patsubst ...)
instead of $(subst m4/,,$@) to substitute only last "m4/" occurence in
path.

+Subject: [PATCH] Makefile: fix install failure if path contains "m4/" string
+
+Actually Makefile install recipe substitutes every occurence of "m4/" in
+file name of the target of the rule($@), in an absolute path there could
+more than one "m4/" occurence, so install will fail. Let's change
+$(subst ...) with $(patsubst ...) substituting only last occurence of
+"m4/" pattern.
